Alternative Electrolytes

From Oscomak

In the process of creating oxygen through ceramic electrolysis zirconia and ceria are the main electrolytes used. However, additional possibilities for improving operating conditions and overall efficiency include: Bi₂O₃, (Bi₂O₃)_.75(Y₂O₃)_.25, Ce_.8Gd_.2O_1.9, (La₂O₃)_.95(SrO)_.05, and multiple zirconia including compounds such as: (ZrO₂)_.9(Y₂O₃)_.1, (ZrO₂)_.9(Sc₂O₃)_.1, (ZrO₂)_.87(CaO)_.13, Zr₂Gd₂O₇, and Zr₂Sm₂O₇.

A graph comparing operational temperatures and output conductivity of these compounds can be found on page six of this document: [1]

Thin films of La_1.61GeO_5−δ have been found to be highly conductive even at lower temperatures.
